The difference between NFC and RFID

Clarifying how NFC and RFID relate to each other

Even after a decade since the term Near Field Communication (NFC) was introduced, I still have clients, advisors and prospective customers ask me if NFC can be used to track physical location or operate at multiple meter ranges. Although NFC is considered a subset of Radio Frequency Identification (RFID) in the hierarchy of electrical engineering applications, there are several distinctions that make them suitable to different applications. NFC is designed to realize a fundamentally different set of features than those supported by traditional UHF RFID.
